Vendetta Online is a multi-platform 3D space-combat MMO for Windows, Mac, Linux/32 and Linux/64. The game permits players to interact in a vast online galaxy; fighting, trading, and mining their way to success. A "twitch" type real-time combat model makes true player skill the deciding factor instead of character advancement. Massive capital-ship battles shake the foundations of the major nations at war, while others struggle to push back the encroachment of the AI "Hives". A no-strings free trial is available.

KaGez-Production aims to make game developing
under Linux easier. Tutorials and examples,
reaching from simple console applications (non-
graphical) to OpenGL games, are available, as well
as tools like Image-Viewers, and 3D-Model viewers.
All applications will be made for Linux only, most
graphical items will work with GTK+/GNOME.

iMaze is a multi-player network action game for TCP/IP with 3D
